How do birds orient themselves with respect to Earth's magnetic field?

Thorsten Ritz presents his research on the magnetic compass of birds, which allows them to navigate accurately throughout long migrations. He explores various methods of magnetic sensing in other organisms and proposes a quantum mechanical solution for birds.

Presented at the Exploratory Workshop on Nontrivial Quantum Effects, Anacapri, Italy, October 2010
